I don't know why, but every time I see the Twilight Princess style of having the blade be longer than before, It always looks like it's unbalanced, that you'd waste more energy trying to hold it, let alone swing it with one hand

It's a decent design. But I'm deffinatley one of those who would've prefered if Nintendo would've kept the original design from ALLTP.Can't say that I'm surprised that they changed it though. I would've been more surprised if they actually did keep the original.
